It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The first embodiment is as follows:

as shown in fig. 1, 2 and 3, a dust catching net device in a coal mine comprises a door type dust catching net 1, a sliding groove 3 arranged on a vertical frame 2 at two sides of the door type dust catching net 1, an elastic reset clamping seat 4 arranged on the sliding groove 3, an opening and closing clamping plate 6 hinged on a bottom transverse frame 5 of the door type dust catching net 1 and the vertical frame 2, a positioning part 7 arranged between the opening and closing clamping plate 6 and the bottom transverse frame 5 and between the vertical frames 2, and a pull rope 8 arranged in the vertical frame 2 and connected with the elastic reset clamping seat 4, wherein the elastic reset clamping plate 4 can be pulled to move on the sliding groove 3 through the pull rope 8.

In this embodiment, as shown in fig. 3, the elastic reset holder 4 includes an elastic band 9 disposed at two ends of the top cross frame 15 of the door type dust catching net 1 and a holder 10 connected to a lower end of the elastic band 9, and the elastic band 9 is connected to the holder 10 to drive the holder 10 to rebound to an upper end of the sliding chute 3.

In this embodiment, as shown in fig. 3, the positioning element 7 includes a positioning pin 11 disposed on the inner wall of the opening and closing clamp plate 6 and a pinhole 12 disposed on the vertical frame 2 and the bottom horizontal frame 5 and corresponding to the positioning pin 11, and the positioning pin 11 and the pinhole 12 are connected by a magnetic attraction manner. The positioning pin 11 can penetrate through the surface of the dust catching net and be inserted into the pin hole 12 to fix the dust catching net.

In this embodiment, the clamping seat 10 includes a bottom plate 10.1 fixedly connected with the sliding block of the sliding chute 3 and a clamping plate 10.2 hinged with the bottom plate 10.1; a corresponding pinhole 12 and a positioning needle 11 are arranged between the bottom plate 10.1 and the clamping plate 10.2. The two sides of the upper end of the dust catching net can be clamped and fixed through the bottom plate 10.1 and the clamping plate 10.2 of the clamping seat 10.

In this embodiment, as shown in fig. 3, positioning holes 13 are formed on two side walls of the upper and lower ends of the chute 3; and plunger pins 14 corresponding to the positioning holes 13 are arranged on two side surfaces of the sliding seat of the sliding groove 3. The positioning hole 13 and the plunger pin 14 are used to position the position where the cartridge 10 moves within the chute 3.

The specific implementation mode is as follows: the clamping seat 10 is pulled downwards along the sliding chute through the pull rope 8, when the sliding seat drives the clamping seat 10 to move to the position of a positioning hole 13 at the lower end of the sliding chute 3, a plunger pin 14 on the side surface of the sliding seat pops out and is clamped into the positioning hole 13, and therefore the position of the clamping seat 10 is positioned; clamping the lower end edge of a dust catching net without a frame between a bottom cross frame 5 and an open-close plate 6, clamping two ends of the upper end cross edge of the dust catching net between a bottom plate 10.1 of a clamping seat 10 and a clamping plate 10.2, pushing the clamping seat 10 upwards to enable a plunger pin 14 to slide out of a positioning hole 13 at the lower end of a sliding chute 3, wherein when the clamping seat 10 does not have the positioning hole 13 and the plunger pin 14 to be limited correspondingly, the resilience force of an elastic belt 9 can automatically drive the clamping seat 10 to move upwards along the sliding chute 3, and the lower end edge of the dust catching net is clamped on the bottom cross frame, so that the clamping seat 10 clamps the upper end edge of the dust catching net to move upwards and naturally stretches the net body of the dust catching net; when the holder 10 moves to the upper end of the sliding chute 3, the plunger pins 14 at the two sides of the sliding seat can be clamped into the positioning holes 13 at the upper end of the sliding chute 3 to position the holder 10 and enhance the stability of the holder 10. At this moment, the quick installation of the dust catching net is completed.

When the dust catching net needs to be detached and replaced, the vertical frame 2 opening plate 6 is opened, the clamping seat 10 is pulled down to the lower end of the sliding groove 3 through the pull rope 8, the bottom plate 10.1 and the clamping plate 10.2 are opened, the dust catching net is taken out from the clamping seat 10 and the vertical frame 2, the bottom transverse frame 5 and the opening plate are opened at last, the lower end edge of the dust catching net is taken out, and the dust catching net is rapidly detached at the moment.

The foregoing description is only exemplary of the preferred embodiments of the application and is provided for the purpose of illustrating the general principles of the technology and the like. Meanwhile, the scope of the invention according to the present application is not limited to the technical solutions in which the above-described technical features are combined in a specific manner, and also covers other technical solutions in which the above-described technical features or their equivalent are combined arbitrarily without departing from the inventive concept described above. For example, the above features and the technical features disclosed in this application but not limited to having similar functions are mutually replaced to form the technical solution.
